Answer:
The equation is q + 10 = 20
The solution is q = 10
Step-by-step explanation:
"sum" means an addition.
"sum of q and 10" means "q + 10".
"is" means "="
That means you have the equation
q + 10 = 20
To solve the equation, subtract 10 from both sides.
q + 10 - 10 = 20 - 10
q = 10
Answer:
The equation is q + 10 = 20
The solution is q = 10
